Mr. Arella and Ms. Biernat will work together on product development, with Mr. Arella focusing a bit more on administration and operations, Ms. Biernat said. Mr. Arella was director with a focus on risk management, evaluation and monitoring, as well as on business management. He will remain a member of the investment committee and the risk management committee at the hedge fund-of-funds manager, Ms. Biernat said.
